Semicircular Bedding Block for Rifle Action Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rifle bedding blocks fail to provide a stable and precise fit between the barreled action and the stock, leading to movement during firing, which affects accuracy and precision, and often require additional bedding material, limiting versatility.
Innovation Solution
A bedding block with a semicircular channel and resilient sidewalls that creates an undersized interference fit with the barreled action, eliminating the need for additional bedding material and allowing use with multiple rifles while maintaining accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a V-shaped channel bedding block is used to interface with the barreled action, then the action can be mounted to the stock, but the fit is not exact and stable, causing movement during firing and declining accuracy
Solution Approach 1:
The patent applies curvature by replacing the conventional V-shaped channel with a semicircular channel having a radius of curvature. This curved geometry provides a more precise and stable interface with the barreled action, eliminating movement during firing while maintaining manufacturing feasibility. The semicircular shape naturally conforms to the action contours, ensuring consistent contact and precision without requiring additional bedding material.
2Reliability
If bedding material is added around the action to hold it stationary in the bedding block, then stability is improved, but the versatility of the stock is limited to one cartridge and magazine configuration
Solution Approach 1:
The patent achieves universality by designing a semicircular channel with specific dimensional tolerances that can accommodate multiple barreled actions of different calibers and configurations. The channel geometry and undersized radius create a stable fit for various actions without requiring additional bedding material, allowing the stock to be used with different cartridge and magazine configurations while maintaining accuracy and precision.
3Device complexity
If an undersized semicircular channel is used to create an interference fit, then the need for additional bedding material is eliminated, but the channel geometry must be precisely controlled
Solution Approach 1:
The patent applies parameter changes by specifying a radius for the semicircular channel that is intentionally smaller than the radius of the barreled action. This undersized radius creates an interference fit that eliminates the need for additional bedding material. The precise control of this radius parameter ensures consistent, stable fits across multiple actions while maintaining relatively simple manufacturing processes.

AI summary
A bedding block for mounting a barreled action for a rifle to a stock can include an elongated body configured to receive the barreled action for the rifle in a semicircular channel defined in top surface of the elongated body. The semicircular channel can have a first radius, the barreled action can have a second radius, and the first radius can be less than the second radius.
